A 79-year-old Long Island woman has been granted what’s believed to be the state’s first contested no-fault divorce.

Gloria Sorrentino wanted out of her 56-year union to Sebastian Sorrentino on the grounds their marriage was “irretrievably broken.”

But her husband wanted to stay hitched, and contended that two of their four kids were pressuring her into dumping him.

Applying the state’s year-old no-fault divorce law, Suffolk County Supreme Court Justice James Quinn sided with the wife after determining at a trial that their marriage was done.

The wife, he noted, testified that they “have not had marital relations in excess of five years, and although they live in the same house, they sleep in separate bedrooms, and never have meals together.”

The Dix Hills couple also “spend no holidays together and share no common friends,” and only the mom socializes with their kids.

And even though she’s in poor health, her hubby “has not taken her to her doctor’s appointments in the last five years, nor has he asked about her health for the past ten years,” the judge wrote.

“The plaintiff testified that she has no hope for the marriage … and that her only wish is for a divorce so that she can have one-half of her marital assets and leave them to her four children before her demise,” according to court papers.

Sebastian Sorrentino said he “worked hard to acquire everything the parties had” and didn’t want to lose it in a divorce.

“[I]t is this Court’s determination that the parties’ relationship has so deteriorated irretrievably …the plaintiff is entitled to a judgment of absolute divorce,” Quinn wrote.

The decision is groundbreaking – the New York Law Journal says it’s likely the first time no fault has been applied in a contested split.

Under the old law, spouses had to blame their partners for the breakdown of the marriage on grounds such as adultery, cruelty or abandonment.

State legislators added the no-fault provision in late 2010, in hopes that doing so would remove some of the bad blood from the divorce process, and allow couples who both wanted to break up to part ways without having to “invent false justifications for the split.”

Under no-fault, only one spouse has to say the marriage has been irretrievably broken down for six months. Until now if’s been used almost exclusively in amicable breakups.

Sorrinto’s daughter, Gloria Kleet, said her mom was thrilled when her lawyer called her last week with the news.

“She was so happy because my father used to always say she’d never get it,” Kleet said.

“She’s been trying this for over 20 years. My mother was always afraid of him,” Kleet said. “They don’t get along. [The marriage] is just broken.”

She said her mom is hoping to move out of the home she still shares with her now-ex.

“She just wants peace and happiness and to be with her grandkids and her children. That’s all she wants,” Kleet said.
